Genera
Medicago
Medicago (family: Fabaceae, the pea family) is a genus of perennial flowering plant, known generally as medick or burclover. The most prominent member of the genus is alfalfa (M. sativa), an important crop. [more]
Melanorrhoea
Melilotus
Melilotus, known as Melilot or Sweet-clover, is a genus in the family Fabaceae. Members are known as common grassland plants and as weeds of cultivated ground. Originally from Europe and Asia, it is now found worldwide. [more]
Ononis
Ononis is a large genus of perennial herbs and shrubs from the legume family Fabaceae. The members of this genus are often called restharrows as some species are arable weeds whose tough stems would stop the harrow. They are natively distributed in Europe. [more]
Onychium
Ophiocaulon
Parochetus
Parochetus is a genus of perennial herbs. [more]
Pereskia
Pereskia is a genus of about 25 tropical species and varieties of cacti that do not look much like other types of cacti, having substantial leaves and thin stems. They originate from the region between Brazil and Mexico. The genus is named after Nicolas-Claude Fabri de Peiresc, a 16th century French botanist, which also has been given its own subfamily Pereskioideae. Members of this genus are usually referred to as lemon vines, rose cacti or leaf cacti, though the latter also refers to the genus Epiphyllum. [more]
Trifolium
Clover (Trifolium), or trefoil, is a genus of about 300 species of plants in the leguminous pea family Fabaceae. The genus has a cosmopolitan distribution; the highest diversity is found in the temperate Northern Hemisphere, but many species also occur in South America and Africa, including at high altitudes on mountains in the tropics. They are small annual, biennial, or short-lived perennial herbaceous plants. The leaves are trifoliate (rarely 5- or 7-foliate), with stipules adnate to the leaf-stalk, and heads or dense spikes of small red, purple, white, or yellow flowers; the small, few-seeded pods are enclosed in the calyx. Other closely related genera often called clovers include Melilotus (sweet clover) and Medicago (alfalfa or 'calvary clover'). The "shamrock" of popular iconography is sometimes considered to be young clover. The scientific name derives from the Latin tres, "three", and folium, "leaf", so called from the characteristic form of the leaf, which has three leaflets (trifoliate); hence the popular name trefoil. Clovers are used as food plants by the larvae of some Lepidoptera (butterfly and moth) species; see list of Lepidoptera that feed on clovers. [more]
Trigonella
Trigonella is a large genus from the family Fabaceae, with about 130 species. The best known member is the herb Fenugreek. [more]
At least 190 species and subspecies belong to the Genus Trigonella.
